- The pool-volume example specifies a 16-by-38-foot pool with Roman ends and a sloped bottom, then gives a checkable estimate of 20,700 gallons.
Field notes
The homepage organizes its calculators by task, with separate sections for water volume, chemistry, equipment and costs, plus aquarium tools. Its examples name practical inputs—including pool dimensions, test readings, hose flow and pump turnover—and describe outputs in usable units such as gallons, litres, ounces, pounds and bags. The chemistry section also says its dosing plan gives an order for additions and allows smaller amounts to be retested.
